Geotechnical Instrumentation

Overview

Determination of engineering properties of soil is essential for foundation design, earthwork construction, slope stability analysis, and pavement design. Every geotechnical investigation programme requires standardised soil testing equipment that delivers reliable, repeatable results.

AG Measurematics manufactures soil testing equipment that meets IS 2720, ASTM, BS 1377, and AASHTO requirements — with digital instrumentation, motorized loading, and automated data acquisition for modern geotechnical laboratories.

  • CBR, triaxial, consolidation, direct shear, and UCS testing
  • Digital load cells and LVDT displacement sensors
  • Automated data acquisition with PC software
  • IS 2720, ASTM D-series, BS 1377, AASHTO compliant
  • Motorized loading with programmable strain rates
  • Used by geotechnical consultants and engineering colleges

Features

Key Features

Multi-Standard Compliance

All equipment pre-configured for IS 2720, ASTM D-series, BS 1377, and AASHTO standards — with built-in test procedures and reporting templates for each standard.

Digital Instrumentation

Precision load cells and LVDT displacement sensors replace dial gauges and proving rings — providing higher accuracy, automatic data capture, and elimination of human reading error.

Automated Data Acquisition

PC-based data acquisition with real-time display of test parameters, automatic logging at user-defined intervals, and one-click test report generation.

Motorized Loading

Programmable strain-rate controlled loading for CBR, triaxial, and direct shear tests — eliminates operator variability and ensures standard-compliant loading rates.

Robust Construction

Heavy-duty load frames with powder-coated finish, corrosion-resistant hardware, and industrial-grade components designed for continuous laboratory use.

Complete Turnkey Systems

Supplied as complete packages with all required accessories, transducers, software, and documentation — ready for immediate testing after installation.
